Product Characteristics
Integrated Standard B5 Flange Structure
Adopts universal IEC B5 motor direct connection flange with one-piece casting design, no extra adapter plate required. High positioning accuracy and low coaxial error ensure flat contact surface without shaking during assembly.
Wide Stepless Mechanical Speed Regulation
Continuous adjustable speed ratio from 1:1.4 to 1:7 with regulation precision up to 0.5-1 RPM. Smooth speed transition without gear gaps, supporting stable clockwise and counter-clockwise continuous operation.
High-Strength Sealed Aluminum Alloy Housing
Die-cast aluminum alloy box with thickened alloy steel transmission parts. Double skeleton oil seal fully sealed design prevents dust and oil leakage, excellent heat dissipation for long-time non-stop operation.
Product advantages
ompact Layout & Lower Installation Cost
Vertical direct B5 flange connection removes mounting brackets, minimizing overall size. No extra reserved space on machine frames, cutting assembly time and frame processing expenses.
Low Noise & Stable Operation with Low Failure Rate
Precisely ground transmission parts with even meshing clearance reduce vibration and running noise. Direct flange connection eliminates coupling gaps to avoid impact load, slowing wear of bearings and friction discs.
Wide Compatibility & Easy Replacement
Globally standard B5 flange dimension allows direct replacement of imported speed variators of same size. Can combine with worm, helical and bevel gearboxes to expand torque, widely used in conveying, packaging, food and textile production lines.

FAQ
Q: What power range of motors is compatible with this B5 flange variable speed gearbox?
A: Standard models fit IEC B5 flange motors from 0.18kW to 7.5kW. Custom larger flanges are available for high-power motors according to load torque demand.
Q:Can this gearbox be combined with other reducers?
A: Yes. The output shaft can connect with NMRV, helical or bevel gear reducers to realize stepless speed control plus multi-stage reduction for high-torque low-speed working conditions.
Q: Will output torque decrease noticeably when adjusting speed?
A:Torque remains stable at low speed and slightly drops at high speed. Pair with rear-end reducers if constant high torque across full speed range is required.
